The Diagnostic and Statistical Manual of Mental Disorders (DSM) refers to manuals published by the American Psychiatric Association (APA). The current DSM is a diagnostic tool aimed at health professionals, and is used in several countries. Early versions of the DSM incorporated statistics, hence “statistical” in its title.
